Video: How to Build Your Own Spiral Staircase Using a CNC Router
This article details the construction of a contemporary spiral staircase using readily available materials and digital fabrication technology. Ben Uyeda of HomeMade Modern demonstrates a method for building a sleek spiral staircase primarily from plywood and a standard steel post. The process leverages a CNC router to precisely cut 12 incrementally sized shapes from a plywood sheet. These shapes are then stacked and secured around the central steel post to form the staircase. HomeMade Modern provides the CAD files for free, allowing individuals with woodworking skills to replicate the project.
The material cost for this DIY spiral staircase is significantly lower than that of prefabricated metal spiral staircases. Uyeda estimates each full step requires approximately 1.25 sheets of 4-foot by 8-foot, 3/4-inch plywood, with each sheet costing around $40. The steel post adds an estimated $450, and screws and glue contribute an additional $200. While the material savings are substantial, the construction process is labor-intensive, requiring approximately two hours per stair. This highlights a trade-off between cost savings and the time commitment involved in digital fabrication projects.
The article also touches upon HomeMade Modern's collaboration with AutoDesk and their new BUILD Space. This 34,000-square-foot facility in South Boston, Massachusetts, serves as a coworking and shop environment dedicated to exploring the potential of digital fabrication technologies. The BUILD Space offers various workshops, including metal fabrication, CNC and manual machining, woodworking, waterjet cutting, large-format routing, laser cutting, composites, glass, robotics, and 3D printing. This partnership underscores the growing accessibility and application of advanced manufacturing techniques in DIY and architectural projects. HomeMade Modern's website offers comprehensive instructions and CAD files for a diverse range of DIY projects, promoting a hands-on approach to modern design and construction.
